Creating water gaps

[bigyihsuan]

I want to create water gaps, similar to the ones found in the Appalachians.

According to Wikipedia, water gaps happen when a river is older than the surrounding, uplifted land, leading to cutting a notch into the ridges it passes through.

I have a sketch world that somewhat does this: an Erosion node with minimal erosion settings, with uplift turned on, and a mask of ridges. This leads to this sort of water gap as a result, but it leaves these nasty spikes where the uplift touches the river:

Any other ideas?

River node with big Valley width or big Bank width and you done

With Reach Creator you may craft own settings for better gap and river shape

default Create Water not best in meaning of wide rivers configuration abilities

but i may be wrong
